What's the behavior of $attribute->getFrontendInput() method?

Question

Can someone explain me what's the behavior and the return value of $attribute->getFrontentdInput()?

I'm using Magento 2.2.7.

Answer 1

The $attribute->getFrontentdInput() method returns the way your attribute is rendered, some values are:

text -> is rendered as input
select -> is rendered as select-one
boolean -> is rendered as a switch (On/Off)

There are also other values.

You can check them by looking at the eav_attribute table which stores all the attributes that are in your Magento installation (see the frontend_input column).

This is a screenshot from my Magento installation:
